Notes:
*) Bits 4 to 7 of the digital NCK outputs can be processed by the PLC even though there are no equivalent hardware I/Os.
These bits can therefore also be used for data exchange between the NCK
and PLC. **) With the 840D, the NCK digital inputs and outputs 1 to 4 are provided as onboard hardware inputs and
outputs. These can be processed by the PLC according to *).
